WKT or GEOJson?

[Riccardo]

Hello everybody.

Qlik Sense GeoAnalytics, which format uses to show a point, polygon, multipolygon, on the map?

WKT or GeoJson?

Ex. WKT:
POINT (42.123,11.123)
POLYGON ((...
MULTIPOLYGON (((...

Ex. GeoJson:
[42.123,11.123]
[[...
[[[...

Can you please reference me to some official documentation?

Thank you very much, regards.

Riccardo

Hi,

The internal Sense geometries (both QGA and map chart) are using GeoJSON geometries.

• Point - a point geometry, i.e. "[longitude,latitude]"
• Line - a line geometry, i.e. "[[longitude,latitude],[longitude,latitude],...]"
• Polygon - a polygon geometry, i.e. an array of closed lines or array of array of closed lines in case of multi-polygons

([long,lat] is a point, [[long1,lat1],[long2,lat2],...] is a line, [[[long1,lat1],[long2,lat2],...]] is a multi-line or a polygon with multiple rings, [[[[long1,lat1],[long2,lat2],...]]] is a multi-polygon but also accepted as a multi-line).

The QGA connector and GeoOperations reads and import WKT (and GeoJSON among others).
